3. Place the triangular prism on the whiteboard with the triangular edge facing down, as shown in the top view diagram below. Shine the red (in-person) laser at one edge of the prism such that it has a large angle of incidence, as shown. For the remote section: Make sure that the "reflections” box is checked. a) How many rays of light leave the prism? Make a sketch on the diagram and record any additional observations. b) For each of the rays that leave the prism, state how many reflections and refractions occurred. Indicate these on the diagram and sketch the path that light travels. c) Describe what happens if you decrease the angle of incidence, as shown at right. Record your observations using both diagrams and words.
2. The top of the lens is covered with a black index card, as shown in the diagram below, what will happen to the image of the pencil? Sketch a ray diagram and explain your reasoning. Hint: How many rays leave each point of the pencil? 4 3. The top of the lens is covered with a black index card, as shown in the diagram below, what will happen to the image of the pencil?
